Yunus was a follower of Khan Abdul Ghaffar Khan, with whom he worked from 1936 to August, 1947 as a Khudai Khidmatgar.[1][3] He was imprisoned during the Quit India Movement by Iskandar Mirza in 1941.[1] In Abbottabad Prison he contracted tuberculosis and was subsequently released in 1944, as the government did not think he would survive. After recuperating, he was again jailed in Kashmir in 1946.

In 1975 he was appointed as special envoy of the then Prime Minister Indira Gandhi. In this capacity he established the Pragati Maidan in Delhi and went on regular trade exhibitions around the globe to promote Indian products and companies.[4]

The first book written by Yunus was titled Frontier Speakers , with a foreword by Jawaharlal Nehru and a preface by Khan Abdul Ghaffar Khan. It was banned by the British government in 1942. He then wrote "Kaidi ke Khat", in Urdu, later translated into English and Hindi, and finally his memoirs, Persons, Passions and Politics published in November 1979.
